This update provides the corresponding update for GnuPG 2\nin Ubuntu 16.04 LTS and Ubuntu 14.04 LTS.\n\nOriginal advisory details:\n\n Marcus Brinkmann discovered that during decryption or verification,\n GnuPG did not properly filter out terminal sequences when reporting the\n original filename. An attacker could use this to specially craft a file\n that would cause an application parsing GnuPG output to incorrectly\n interpret the status of the cryptographic operation reported by GnuPG.\n",
